13 - 18 6.7L Dodge Cummins

by S&B
SKU NWD-77-1000


With all the new emissions requirements, Cummins has transitioned to a closed crankcase ventilation (CCV) system. This can result in a buildup of oil residue inside your intake system and reduce the performance and potentially accelerate the wear and tear on engine components. Our Open CCV Kit for the 2007-2018 Dodge Cummins 6.7L trucks will keep your intake tube, turbo and intercooler free of oily crankcase buildup.

  1. Can I delete the ccv filter under the valve cover when using this product?

    A: The oem crankcase filter is capturing most of the oil vapors in the blow-by gases. The breather filter is not designed to provide the same functionality and may get saturated with oil vapors quickly if the oem crankcase filter is removed. S&B does not recommend removing the oem crankcase filter.

  2. Will I need a tuner to use this product without getting a check engine light?

    A: Yes, in most situations, a custom tune or programmer will be required to use this product without getting an check engine light.

  3. Will oil leak out from the crankcase?

    It is possible that some oil may leak out of the filter, however the 90 degree elbow we have provided helps to minimize oil leakage and redirect oil back into the crankcase. Over time, the breather filter may become saturated with oil and may start dripping slowly. Cleaning the crankcase filter as described below will regularly will prevent this from happening.

  4. Does S&B make a similar product for other applications?

    S&B’s engineering team is currently researching other applications for this product. You can track our progress on the R&D page of our website.

  5. How do I clean the S&B crankcase filter?

    A: Wash the S&B crankcase filter with warm, soapy water and rinse thoroughly. Allow the filter to air dry or place it in front of a small fan. Do not use a hair dryer as the hot air can damage the filter media.
